1. General Description

The LD750DGN is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED)

backlight system. The matrix employs a-Si Thin Film Transistor as the active element.

It is a transmissive display type which is operating in the normally black mode. It has a 74.52 inch diagonally

measured active display area with QWUXGA resolution (2160 vertical by 3840 horizontal pixel array).

Sub-pixels are constructed with Red, Green, Blue and White. Each pixel is divided into RGB or WRG or BWR

or GBW or dots which are arranged in vertical stripes.

Gray scale or the luminance of the sub-pixel color is determined with a 10-bit gray scale signal for each dot.

Therefore, it can present a palette of more than 1.07Bilion colors.

It has been designed to apply the 10-bit 8 Lane V by One interface.

It is intended to support Commercial Display where high brightness, super wide viewing angle, high color

gamut, high color depth and fast response time are important.

2. Temperature and relative humidity range are shown in the figure below.

Wet bulb temperature should be Max 39°C, and no condensation of water.

3. Gravity mura can be guaranteed below 40°C condition.

4. The maximum operating temperatures is based on the test condition that the surface temperature

of display area is less than or equal to 68°C with LCD module alone in a temperature controlled chamber.

Notes :

1. Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately 60

minutes at 25±2°C. The specified current and power consumption are under the typical supply Input voltage

24Vand VBR (ExtVBR-B : 100%), it is total power consumption. 2. LGD recommend that the PWM freq. is synchronized with One time harmonic of V_sync signal of system.

Though PWM frequency is over 120Hz (max 252Hz), function of LED Driver is not affected. 3. The duration of rush current is about 200ms. This duration is applied to LED on time

4. Even though inrush current is over the specified value, there is no problem if I2T spec of fuse is satisfied.

5. Ext_PWM Signal have to input available duty range.

Between 99% and 100% ExtVBR-B duty have to be avoided. ( 99% < ExtVBR-B < 100%)

But ExtVBR-B 0% and 100% is possible.

6. The life time is determined as the time at which brightness of the LED is 50% compared to that of initial value

at the typical LED current on condition of continuous operating at 25 2°C, based on duty 100%.

notes : 1. Contrast Ratio(CR) is defined mathematically as :

Surface Luminance with all white pixels Contrast Ratio = Surface Luminance with all black pixels

It is measured at center 1-point.

2. Surface luminance is determined after the unit has been ‘ON’ and 1 Hour after lighting the

backlight in a dark environment at 25±2°C. Surface luminance is the luminance value at center

1-point across the LCD surface 50cm from the surface with all pixels displaying white.

For more information see the FIG. 2 3. The variation in surface luminance , WHITE is defined as :

WHITE(9P) = Minimum (Lon1,Lon2~ Lon8, Lon9) / Maximum (Lon1,Lon2~ Lon8, Lon9)*100

Where Lon1 to Lon9 are the luminance with all pixels displaying white at 9 locations

For more information, see the FIG. 2.

4. Response time is the time required for the display to transit from G(N) to G(M) (Rise Time, TrR) and from G(M) to G(N) (Decay Time, TrD). For additional information see the FIG. 3. (N<M)

※ G to G Spec stands for average value of all measured points.

Photo Detector : RD-80S / Field : 2˚

※. Gray to Gray Response time uniformity is Reference data. Appendix V

5. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which

is normal to the LCD module surface. For more information, see the FIG. 4. 6. Gray scale specification

Gamma Value is approximately 2.2. For more information, see the Table 12.

Please pay attention to the followings when you use this TFT LCD module.

9-1. Mounting Precautions

(1) You must mount a module using specified mounting holes (Details refer to the drawings).

(2) You should consider the mounting structure so that uneven force (ex. Twisted stress, Concentrated stress)

is not applied to the module. And the case on which a module is mounted should have sufficient strength

so that external force is not transmitted directly to the module.

(3) Please attach the surface transparent protective plate to the surface in order to protect the polarizer.

Transparent protective plate should have sufficient strength in order to the resist external force.

(4) You should adopt radiation structure to satisfy the temperature specification.

(5) Acetic acid type and chlorine type materials for the cover case are not desirable because the former

generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break

by electro-chemical reaction.

(6) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB

pencil lead. And please do not rub with dust clothes with chemical treatment.

Do not touch the surface of polarizer for bare hand or greasy cloth.(Some cosmetics are detrimental

to the polarizer.)

(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like

chamois soaks with petroleum benzine. Normal-hexane is recommended for cleaning the adhesives

used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they cause

chemical damage to the polarizer

(8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes

deformations and color fading.

(9) Do not open the case because inside circuits do not have sufficient strength.

(10) Touching the LED Driver might cause an electric shock and damage to LED Driver. Please always use

antistatic tools when handling the LED Driver

9. Precautions

9-2. Operating Precautions

(1) Response time depends on the temperature.(In lower temperature, it becomes longer.)

(2) Brightness depends on the temperature. (In lower temperature, it becomes lower.)

And in lower temperature, response time(required time that brightness is stable after turned on)

becomes longer

(3) Be careful for condensation at sudden temperature change.Condensation makes damage to polarizer or

electrical contacted parts. And after fading condensation, smear or spot will occur.

(4) When fixed patterns are displayed for a long time, remnant image is likely to occur.

(5) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall be

done by system manufacturers. Grounding and shielding methods may be important to minimized the

interference.

(6) Please do not give any mechanical and/or acoustical impact to LCM. Otherwise, LCM can’t be operated

its full characteristics perfectly.

(7) A screw which is fastened up the steels should be a machine screw.

(if not, it can causes conductive particles and deal LCM a fatal blow)

(8) Please do not set LCD on its edge.

(9) The conductive material and signal cables are kept away from LED driver inductor to prevent abnormal

display, sound noise and temperature rising.

Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that

treatment persons are connected to ground through wrist band etc. And don’t touch interface pin directly.

9-3. Electrostatic Discharge Control

Strong light exposure causes degradation of polarizer and color filter.

9-4. Precautions for Strong Light Exposure

When storing modules as spares for a long time, the following precautions are necessary.

(1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the temperature

between 5°C and 35°C at normal humidity.

(2) The polarizer surface should not come in contact with any other object.

It is recommended that they be stored in the container in which they were shipped.

(3) Storage condition is guaranteed under packing conditions.

(4) The phase transition of Liquid Crystal in the condition of the low or high storage temperature will be

recovered when the LCD module returns to the normal condition.

9-5. Storage

28 /40

9-6. Appropriate Condition for Commercial Display

- Generally large-sized LCD modules are designed for consumer applications (TV).

Accordingly, a long-term display like in Commercial Display application, can cause uneven display including

image sticking. To optimize module's lifetime and function, several operating usages are required. 1. Normal operating condition

- Temperature: 0 ~ 40

- Operating Ambient Humidity : 10 ~ 90 %

- Display pattern: dynamic pattern (Real display)

Note) Long-term static display can cause image sticking. 2. Operating usages under abnormal condition

a. Ambient condition

- Well-ventilated place is recommended to set up Commercial Display system.

b. Power and screen save

- Periodical power-off or screen save is needed after long-term display.


LD750DGN

Ver. 1.1 29 /40

3. Operating usages to protect against image sticking due to long-term static display

a. Suitable operating time: under 24 hours a day.

b. Static information display recommended to use with moving image.

- Cycling display between 5 minutes' information(static) display and 10 seconds' moving image.

c. Background and character (image) color change

- Use different colors for background and character, respectively.

- Change colors themselves periodically.

d. Avoid combination of background and character with large different luminance.

1) Abnormal condition just means conditions except normal condition.

2) Black image or moving image is strongly recommended as a screen save.

4. Lifetime in this spec. is guaranteed only when Commercial Display is used according to operating usages.

5. Module should be turned clockwise based on front view when used in portrait mode.
